SDBD and SDBDe

Downblast Direct Drive Centrifugal Roof Exhaust Fans

SDBD and SDBDe direct drive fans are designed to exhaust air up to 4,984 CFM, with high static pressure capability up to 1-1/2". The non-overloading backward inclined wheel with its higher static pressure capability makes these units suitable for either ducted or non-ducted applications. The spun aluminum exterior provides an attractive appearance. Direct drive units use smaller diameter wheels, resulting in low sound levels and quiet operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance. Its roof mounting permits short duct runs and more efficient operation.

SDB

Belt Drive Centrifugal Downblast Roof Exhaust Fan

The SDB belt drive fans are designed to exhaust air up to 31,563 CFM in high static pressure applications up to 1-3/4". The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Model SDB well suited to applications where quiet operation is important. Belt drive also permits easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.
